Following the makefile cross-platform, cross-compiler project methodology, we finally developped a sound makefile project for MOHID.

Features

Global environment variables

There is one thing that allow this project to be easily cross-platformed:

The use of global environment variables. They are all defined in the respective platform makefile: Win.mk, Nix.mk, etc... Every new addition of a module, of a fortran file, or of an action must be followed by an update of all the respective platform makefiles (Win.mk, Nix.mk, etc...)

Platform/Compiler expandible

The project makefile's DAG meta-tree shows currently 4 platforms/compilers available: windows Win.mk, linux Nix.mk, linux with Portland Group Fortran Nix_pgf.mk and macintosh Mac.mk.

To add a new compiler and/or a new architecture, one needs to change the main Makefile and create a new Arch_Fcomp.mk file.

Action extensible

An action is one given process to apply to the whole project: it could be to build the project, to clean the project, to install the binaries of the project to a safe place, to Get the files of the project from SourceOffSite etc ... The makefile code for the actions of the MOHID project is located in the files contained by the makefiles folder (at the bottom of the image).

To add a new action, one needs to edit the Makefiles/Makefiles.mk file and the Makefiles/Makemodules.mk.

Module extensible

The MOHID project has a modular nature. In this makefile project, each module is subject to the same overall actions and each module is contained in a light-blue folder in the image (MohidWater, Mohid_Base_1, Mohid_Base_2 and ...).

To add a new file to an existing module: one must edit the Makefile file within the module's folder.
To add a new module: one must create a new folder, name it after the module, copy the module's files, create the corresponding Makefile file. Finally, one must edit the Nix.mk file from the root folder.

Linux

Build

>make Nix

Please edit the nix_template.mk first and save it as nix.mk

Clean

>make Nix.clean

Please edit the ../makefiles/Sos_template.mk file first and save it as ../makefiles/Sos.mk.

Install

>make Nix.install

This will copy the binaries to a specific location on the harddisk. You can change the location by editing the Nix.mk file.

Windows

Use GNUmake! Attention: Rename gmake.exe to make.exe.

Build

>make win

Clean

>make win.clean

How do I add a new module file in MohidWater?

Suppose your new module filename is MohidWater/ModuleNew.F90, and it depends only on ModuleGlobalData, ModuleWaterproperties.mod and ModuleHydrodynamic.F90. Edit the Makefile file in the Linux/MohidWater folder and...

... look for the FILES variables section:

> vim Solutions/Linux/MohidWater/Makefile
FILES = \
      ModuleNew.$(S) \
      ModuleAssimilation.$(S) \
      ModuleConsolidation.$(S) \
      ModuleFreeVerticalMovement.$(S) \
      ModuleJet.$(S) \
      ...

... look for the Dependencies section at the end:

 ModuleNew.${O} : ModuleWaterProperties.${O} \
                    ModuleHydrodynamic.${O}
ModuleGauge.${O} : ModuleToga.${O}
ModuleSand.${O} : ModuleWaves.${O}
      ...

NOTE: Only the local dependencies of MohidWater are required. The external dependencies of MohidBase1 or MohidBase2 are not required.

That's it! You can now build the Linux solution!

How do I add a new module folder?

Create a new folder (ex: MohidLand),
Copy a regular folder Makefile into the new folder,
Edit the Makefile:
1. Edit the FILES variable
2. Edit the dependencies
3. Assign to variables TARGET and SRCDIR appropriate global variables names
Edit the Nix.mk file:
1. Create the global variables to be assigned to TARGET and SRCDIR (make sure the variable to be assigned as TARGET ends in $(SUFFPROG) if it's an executable or $(SUFFLIB) if it's a library).
2. Edit the MODULES variable
3. Add the module dependency
